W2CWM2C-package {W2CWM2C}

W2CWM2C: a graphical tool for wavelet (cross) correlation and wavelet multiple (cross) correlation analysis

Description

The W2CWM2C package is a set of functions that improves the graphical presentations of the functions 'wave.correlation' and 'spin.correlation' (wavelet cross correlation) (waveslim package, Whitcher 2012) and the 'wave.multiple.correlation' and 'wave.multiple.cross.correlation' (wavemulcor package, Fernandez-Macho 2012b). The plot outputs (heatmaps) can be displayed in the screen or can be saved as PNG or JPG images or as PDF or EPS formats. The W2CWM2C package also helps to handle the (input data) multivariate time series easily as a list of N elements (times series) and provides a multivariate data set (dataexample) to exemplify its use. A description of the package was published by Polanco-Martinez and Fernandez-Macho (2014), <doi:10.1109/MCSE.2014.96>.

The W2CWM2C package contains four functions: (1) WC that performs and plots the wavelet correlation for the bivariate case, (2) WCC that performs and plots the wavelet cross correlation for the bivariate case, (3) WMC that performs and plots the wavelet multiple correlation for the multivariate case, and 4) WMCC that performs and plots the wavelet multiple cross correlation for the multivariate case.

Note

Dependencies: waveslim, wavemulcor and colorspace.
